Description
Technical field
The utility model belongs to industrial high temperature flue gas ash removal field, particularly relates to a kind of novel sack cleaner that is used for the industrial high temperature flue gas ash removal.
Background technology
Steel industry is carried out (GB9078-1996) middle dust pelletizing system concentration of emission requirement of national standard " industrial furnace atmosphere pollutants emission standards " at present.The Shanghai regional standard had been finished revision in 2009, " Shanghai City steel and iron industry atmosphere pollutants emission standards " regulation: existing source is 60 mg/m
3, new source 30 mg/m
3
Along with the variation of the fast development of China's steel and iron industry and structural adjustment in recent years and production pattern, existing discharge standard is carried out strict control to the discharging of dust granules thing, and the equipment technology that adopts has been difficult to satisfy the environmental requirement of energy-saving and emission-reduction at present.
Chinese industrial particle dust discharge amount was 670.7 ten thousand tons in 2008, and steel industry accounts for 15% of national dust discharge amount.The sack cleaner of iron and steel metallurgical industry use at present mostly is middle part flue ash bucket air inlet structure form, this version makes that smoke inlet speed is too high, the air-flow skewness, and cause dust granules secondary back-mixing in the ash bucket, cause the filter bag dust load to increase the weight of, the deduster running resistance increases, and to all having a strong impact in sack cleaner service life and dust removing effects, does not meet the energy-saving and emission-reduction development policies.Require the new reorganization and expansion task of the soot emissions deduster that brings up to standard to the application of novel sack cleaner provide for a long time, reliable market.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, provide in a kind of solution prior art smoke inlet speed too high, the air-flow skewness, cause the problem of dust granules reentrainment of dust in the ash bucket, and by-pass flue can make deduster under the situation of operation, and the novel sack cleaner that is used for the industrial high temperature flue gas ash removal with precoating dirt is overhauled in the bag chamber.
The utility model adopts technical scheme as follows:
A kind of novel sack cleaner that is used for the industrial high temperature flue gas ash removal, it is characterized in that it comprises the air inlet ash bucket, inlet channel, the exhaust passage, air intake valve, drain tap, on take off cover plate, the winding-up gas bag, the row winding-up, by-pass flue, bypath valve and bypass ash bucket, the double-deck flap valve of weight is housed in described air inlet ash bucket and the bypass ash bucket, described inlet channel and exhaust passage lay respectively at deduster body both sides, described air intake valve is loaded in the inlet channel, described drain tap is loaded in the exhaust passage, described bypath valve is loaded in the by-pass flue, described winding-up gas bag is bivalve pattern gas bag side by side, and is positioned at dust remover roof.
Described air inlet ash bucket, inlet channel, exhaust passage, air intake valve, drain tap, on to take off unit that cover plate, winding-up gas bag, row winding-up, by-pass flue, bypath valve and bypass ash bucket form single or at least two and be unified into deduster.
The beneficial effects of the utility model have:
The utility model is arranged in the side of deduster with the flue gas inlet channel, has avoided smoke inlet speed too high, the air-flow problem of uneven distribution; Simultaneously, use the double-deck flap valve of weight and side by side dual valve type gas bag structure make automatic ash-discharging more effective; Gas bag, pneumatic operated valve adopt gas circuit and air accumulator separately, and independent generation of each system influences each other, and system stable operation, increase service life; Increase by-pass flue, when the convenient bag chamber goes wrong, can under the deduster operation conditions, overhaul; When flue gas directly entered exhaust pass by by-pass flue, the dust of sedimentation can be laid down by the bypass ash bucket.Below all improved the whole dust removing effects of clarifying smoke system, made the soot emissions requirement that is up to state standards.
Description of drawings
Fig. 1 is the utility model vertical view.
Fig. 2 is the utility model front view.
Fig. 3 is the utility model side view.
Wherein: 1-air inlet ash bucket, 2-inlet channel, 3-exhaust passage, 4-air intake valve, 5-drain tap, take off cover plate on the 6-, the 7-gas bag of jetting, the capable winding-up of 8-, 9-by-pass flue, 10-bypath valve, 11-bag-type dust district, 12-smoke inlet, 13-exhanst gas outlet, 14-bypass ash bucket.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As Figure 1-3, the utility model comprises air inlet ash bucket 1, inlet channel 2, exhaust passage 3, air intake valve 4, drain tap 5, on take off cover plate 6, winding-up gas bag 7, row winding-up 8, by-pass flue 9, bypath valve 10 and bypass ash bucket 14, the double-deck flap valve of weight is housed in air inlet ash bucket 1 and the bypass ash bucket 14, inlet channel 2, exhaust passage 3, by-pass flue 9 all is positioned at deduster body both sides, air intake valve 4 is loaded in the inlet channel 2, drain tap 5 is loaded in the exhaust passage 3, bypath valve 10 is loaded in the by-pass flue 9, winding-up gas bag 7 is bivalve pattern gas bags side by side, is positioned at dust remover roof.Air inlet ash bucket 1, inlet channel 2, exhaust passage 3, air intake valve 4, drain tap 5, on take off unit that cover plate 6, winding-up gas bag 7, row winding-up 8, by-pass flue 9, bypath valve 10 and bypass ash bucket 14 form can be single or at least two and be unified into deduster.
As Fig. 1, Fig. 2, Fig. 3, during the utility model work, ash-laden gas enters air inlet ash bucket 1 by smoke inlet 12, big dust particle is because effects such as inertial collision, natural subsidence directly fall into air inlet ash bucket 1, all the other dust are crossed inlet channel 2 with air communication and are entered bag-type dust district 11 and filter, and the clean gas after the filtration 3 is discharged from the exhaust passage.The dust that accumulates in the air inlet ash bucket 1 is realized automatic ash-discharging by the double-deck flap valve of weight; The dust that accumulates in bag-type dust district 11 is by winding-up gas bag 7 gas jet, forms air wave, comes off thereby make filter bag produce rapid expansion and impact shock.When overhaul or during precoating dirt the bag chamber, can keep deduster to continue operation, open bypath valve 10, close air intake valve 4, ash-laden gas directly enters by-pass flue 9 by inlet channel 2, enters exhaust pass through bypath valve 10, and big dust particle is through effects such as inertial collision, natural subsidence, fall into bypass ash bucket 14, the dust that accumulates in the air inlet ash bucket 14 is realized automatic ash-discharging by the double-deck flap valve of weight.
Other undeclared part that the utility model relates to is same as the prior art.
